How do you use the product rule to find the derivative of y=x2⋅sin(x)y=x^2*sin(x) ?

zvonat [6]

$(f(x)\cdot g(x))'=f'(x)\cdot g(x)+f(x)\cdot g'(x)\\\\
y=x^2\sin x\\
y'=2x\cdot \sin x+x^2\cdot \cos x\\
y'=x(2 \sin x+x\cos x)$

Step-by-step explanation:

1) find common denominator, 15 in this problem

$\frac{4}{5}= \frac{12}{15}$

2) solve

$\frac{12}{15}- \frac{8}{15} = \frac{4}{15}$

Answer:

c=45

Step-by-step explanation:

by the pythagorean theorem, c = sqrt(3^2+6^2) = sqrt(9+36) = sqrt(45)

Therefore, c=45.

Answer:

x-intercept (2,0) or x=2

y-intercept (0,-4) or y=-4

Step-by-step explanation:

4x-2y>8

2x-y>4

2x-4>y

y<2x-4

y=2x-4

when y=0

2x=4

x=2

x-intercept is (2,0)

and y-intercept is (0,-4)

put x=0,y=0

0-0>8

or 0>8 which is not true. so (0,0) does not lie on the graph.

so graph lies right of the line .

Graph and write solution: 2x + 1 = y -4x + 6y = -10

PIT_PIT [208]

The graph is shown in figure below

The Solution Set is (-2,-3)

Step-by-step explanation:

We need to graph the equations and writ the solution.

For graphing we need to find the values of x and y.

For that, we need to solve the given equations:

$2x + 1 = y\\-4x + 6y = -10$

Let:

$2x + 1 = y\,\,\,eq(1)\\-4x + 6y = -10\,\,\,eq(2)$

We can solve this by using Substitution Method.

Putting value of y of eq(1) into eq(2) and finding value of x:

$2x + 1 = y\,\,\,eq(1)\\-4x+6(2x+1)=-10\\-4x+12x+6=-10\\8x+6=-10\\8x=-10-6\\8x=-16\\x=-16/8\\x=-2$

So, value of x = -2

Now put value of x in eq(1) to find value of y:

$2x + 1 = y\\2(-2)+1=y\\-4+1=y\\y=-3$

So, value of y = -3

Plotting on graph: x=-2 and y = -3

The graph is shown in figure below

The Solution Set is (-2,-3)
